Preliminary Results of Environmental Review Virgil C. Summer Nuclear Station Nuclear Regulatory Commission August 26, 2003
Purpose of Todays Meeting 3/4 Discuss NRCs license renewal process 3/4 Describe the environmental review process 3/4 Discuss the results of our review 3/4 Provide the review schedule 3/4 Accept any comments you may have today 3/4 Describe how to submit comments 2
V.C. Summer License Renewal 3/4 Operating license expires in August 2022 3/4 Application requests authorization to operate V.C. Summer for an additional 20 years 3
NRCs License Renewal Review 3/4 Safety review 3/4 Environmental review 3/4 Plant inspections 3/4 Advisory Committee on Reactor Safeguards (ACRS) 4
License Renewal Process Onsite Inspection Inspection Activities Report ACRS ACRS Review Report Safety Review S f t Safety Safety Evaluation Review Report License Renewal Agency Application Hearings* Decision on Application Environmental Scoping Draft Comments Final Review Activities Supplement On Draft Supplement To GEIS To GEIS Formal Public *If a request for hearing is granted Participation 5
National Environmental Policy Act 3/4 NEPA requires Federal agencies to use a systematic t ti approachh to t consider id environmental impacts 3/4 Commission has determined that an environmental impact statement (EIS) will be prepared for a license renewal action 6
Decision Standard for Environmental Review To determine whether or not the adverse environmental impacts of license renewal for V.C.
Summer are so great that preserving the option of license renewal for energy planning decisionmakers would be unreasonable.

Analysis Approach Generic Environmental Impact Statement (GEIS)
Category 1 Category 2 GEIS: Impacts Small GEIS: Analyze Potential At All Sites Sit At All Sites Sit N New IIssue New and YES YES Perform Site-Site- Validated Significant Specific Analysis New Issue?
Info?
NO NO Adopt the No Further GEIS Conclusion Analysis 11
How Impacts are Quantified 3/4 NRC-defined impact levels:
3/4 SMALL: Effectff is not detectable or too small to destabilize or noticeably alter any important attribute of the resource 3/4 MODERATE: Effect is sufficient to alter noticeably, but not destabilize important attributes of the resource 3/4 LARGE: Effect is clearly noticeable and sufficient to destabilize important attributes of the resource 3/4 Consistent with the Council on Environmental Quality guidance for NEPA analyses 12
Environmental Impacts of Operation 3/4 Cooling System 3/4 Transmission Lines 3/4 Radiological 3/4 Socioeconomic 3/4 Groundwater Use and Quality 3/4 Threatened or Endangered Species 13
Cooling System Impacts 3/4Entrainment 3/4Losses from entrainment are compensated by the high reproductive success of the fish species 3/4Impingement 3/4 0.47% of fish standing stock impinged annually 3/4Heat Shock 3/4No fish kills since 1993 mitigations were completed 3/4Complies with SCDHEC NPDES permit 3/4ALL IMPACTS SMALL 14
Radiological Impacts z Addresses exposures to the public and to workers z No Category 2 issues z No new and significant information z GEIS concluded impacts are SMALL 15
Threatened or Endangered Species Bald eagle 3/4Several Federal- and State-listed species potentially in vicinity 3/4Informal Consultation with FWS initiated (http://images.fws.gov) 3/4IMPACTS ARE Canbys SMALL dropwort Carolina (http://nc--es.fws.gov/plant/canbydrop.html)

Potential New and Significant Information 3/4 No new and significant information identified:
- during scoping
- by the licensee
- by the staff 17
Other Environmental Impacts Evaluated
- Urani Uranium mFFuel el Cycle C cle and Solid Waste Management
- Decommissioning 18
Alternatives
- No-action
- New N generationti
- Purchased electrical power
- Alternative technologies
- Combination of alternatives 19
Preliminary Conclusions for Alternatives 3/4 Alternatives ((including g the no-action alternative))
may have environmental effects in many impact categories that reach MODERATE or LARGE significance 20
Impacts of Postulated Accidents 3/4 Design-Basis Accidents 3/4 Severe Accidents 3/4 Severe Accident Mitigation Alternatives (SAMAs) 21
SAMA Evaluation Process 3/4 Characterize overall plant risk 3/4 Identify potential improvements 3/4 Quantify risk reduction potential and implementation costs 3/4 Determine whether implementation of any of the improvements is required to support license renewal 22
Results of SAMA Evaluation 3/4 268 candidate improvements identified in ER 3/4 236 eliminated during the initial, initial qualitative screening 3/4 Remaining 32 SAMAs reduced to 12 based on cost and risk reduction considerations 3/4 Detailed cost/benefit analysis shows none of the 12 remaining candidates are cost beneficial 23
Results of SAMA Evaluation (continued) 3/4 Overall conclusion:
3/4 Additional plant improvements to further mitigate severe accidents are not required at V.C. Summer as part of license renewal 24
Preliminary Conclusion 3/4 Impacts of license renewal are SMALL for all impact areas 3/4 Impacts I t off alternatives lt ti to t license li renewall range from SMALL to LARGE 3/4 The staffs preliminary recommendation is that the adverse environmental impacts of license renewal for V.C. Summer are not so great that preserving the option of license renewal for energy planning decisionmakers would be unreasonable 25
